By running xev and pressing the button, which is on the front edge of the laptop. Having the button there is really inconvenient, as it's easy for a belt buckle or such to accidentally press it. In theory, that should be easily noticed, as the button is translucent and illuminated when wifi is connected (and flashes when attempting to connect). However, the light is not consistent in behaviour. But another suggestion comes from a more modern laptop, which has an aeroplane Fn-key (action/hot key), and that uses 255. So that's 246 / XF86WLAN on an old laptop with a physical button, and 255 / XF86RFKill on a newer laptop with a Fn-key. [ … ] > Back to "send key code". One can but try. Did you check the BIOS, BTW? $ xmodmap -pk or -pke will print what keycodes are available, but I don't claim to know how all this stuff works (if it does). Cheers, David.
